Description

The DTLA-4 represents another refinement of this well-established test of general mental ability. It can be used to evaluate areas of strengths and weaknesses in an individual's cognitive functioning, as well as to diagnose learning disabilities and mental retardation. Eleven subtests assess abilities in 3 general domains: language, attention, and manual dexterity. Included in this are measures of short- and long-term memory and visual-motor integration. The DTLA-4 is normed on more than 2500 children. Issues of reliability and validity are well-researched.

Subtests

The following subtests are contained in the DTLA-4: Word Opposites, Design Sequences, Sentence Imitation, Reversed Letters, Story Construction, Design Reproduction, Basic Information, Symbolic Relations, Word Sequences, and Story Sequences.

Composites

Overall Composite: Because this composite is formed by combining standard scores of all 10 subtests in the battery, it is probably the best estimate of g.

Optimal Level Composite: Because this composite comprises the four highest standard scores made by the subject on the subtests, it is the best estimate of a persons overall potential. In this context, potential means the highest level of performance that an individual is capable of when the inhibiting influences of his or her deficits are disregarded.

Domain Composites: Contrasting composites are provided for three domains: language, attention, and manual dexterity. DTLA-4 includes the following: Verbal Composite, Nonverbal Composite, Attention-Enhanced Composite, Attention-Reduced Composite, Motor-Enhanced Composite, and Motor-Reduced Composite.

Theoretical Composites: Subtests are easily assigned to composites that represent major popular theories. Thus, the subtests can be related to Horn and Cattells fluid and crystallized intelligence, to Jensens associative and cognitive levels, to Dass simultaneous and successive processes, and to Wechslers verbal and performance scales.

Administration and Scoring

A variety of problem solving tasks assessing each domain can be completed in a total time between 1 to 2 hours, usually in one testing session. The resulting raw scores can then be converted easily into standard scores, percentile ranks and age equivalents for each of the 11 subtest and 16 composite scores. An overall cognitive composite score is also obtained.

The new DTLA-5 will be available in May 2017.
